[0005] A server includes a casing, a plurality of hard disks housed in the casing, a power supply, a motherboard, and a SAS card. Each hard disk is provided with a power interface and a data interface, and the SAS card is provided. A second SAS connector is disposed, the motherboard includes a detection switching circuit, a SATA connector, a first SAS connector, and a connector connecting a SAS card. The detection switching circuit is connected to the SATA connector. And the first SAS connector, the first SAS connector is further connected to the second SAS connector, and the detection switching circuit controls the connection between the first SAS connector and the first SAS connector by determining the signal it receives. When the detection switching circuit receives a SATA signal, the detection switching circuit cuts off the connection with the first SAS connector, so that the motherboard passes the detection switching circuit and the SATA connector with a SATA hard disk communication; when the detection switching circuit receives a SAS signal, the detection switching circuit turns on a connection with the first SAS connector, so that the motherboard passes the SAS card, the first SAS Connector, the detection switch Road and the SATA connector to communicate with a SAS hard disk. [0006] Compared with the prior art, the server is configured by disposing the detection switching circuit and the SAS connector on the motherboard, and connecting the connector on the SAS card with the connector on the motherboard.

The server 100 includes a casing 10 and a motherboard that is housed in the casing 10. 20, a power supply 25, a hard monument; 〇Λ Wen Hao early 3 〇 and a SAS card 40. The hard disk unit 30 includes a bracket 32 and a plurality of hard disks 31 housed in the bracket core. The bracket 32 is fixed to the front end portion of the outer casing 1 and has an opening 33 facing the front side of the outer casing 10. The opening 33 allows the user to insert the hard disk 31 into the holder 32 from the front of the servo 100 or to remove the hard monument 31 from the holder 32. The hard disk 31 is a SATA (Sen·"u 1Αα1 Αα~ vanced Technology Attachment, a serial advanced technology attachment) hard disk or a SAS (Serial Advanced Technology At tachment) hard disk. A rear end of each hard disk 31 is provided with a power interface and a data interface 37. The data interface 37 is a SATA interface or a SAS interface. [0009] The motherboard 20 is placed on the bottom surface of the casing 10. The motherboard 2 is provided with a plurality of SATA connectors 22 respectively corresponding to the data interface 37 of the hard disk 31. A detection switching circuit 80, a SAS connector 24 and a PCIE connector (not shown). The SAS card 40 is used to implement a conversion function when the motherboard 2 communicates with the SAS hard disk. The SAS card 40 is provided with a SAS connector 44, and the SAS connector 44 and the SAS connector 24 on the motherboard 20. The SAS card 40 is electrically connected to the PCIE connector of the motherboard 20 through a riser card 28 to communicate with the motherboard 2 through a riser card 70. The detection switching circuit 80 is connected to the SATA connector 22 and the SAS 100113732 form number on the motherboard 20 (Π page 6/13 page 1002022962-0 201243611 connector 24. The power supply 25 is provided with The power supply interface 35 of the hard disk 31 corresponds to a plurality of power supply interfaces (not shown). In the present embodiment, the connector 44 on the SAS card 40 is placed in a level manner to facilitate the connection with the domain board 2D. The SAS is connected to the H24. In this embodiment, if the SAS card 40 is plugged into the server 100 and does not affect the assembly of the servo, the SAS + 4〇 can also be directly plugged into the motherboard. On the PCIE connector, [0010] ο. Referring again to FIG. 2, when the hard disk 31 is a hard disk, the power interface 35 is connected to the power supply interface on the power supply 25 through the cable 60. The data interface 37 (mSATA interface) of the hard disk 31 is connected to the SATA connector 22 on the motherboard 2 via a cable 50. After the server 1 is turned on, the detection switching circuit 80 transmits the SATA. The connector 22 and the SATA cable 50 receive a SATA signal output by the hard disk 31. The switching circuit 80 cuts off the connection with the SAS connector 24 so that the motherboard 20 communicates with the SATA hard disk 31 through the detection switching circuit 8 and the SATA connector 22. ^ [0011] When the hard disk 31 is a SAS hard disk, the power interface 35 is connected to the power supply interface on the power supply 25 through the cable 6.
